Radius 2; tangent to x = 2 and y = -1 and above and to the right of these lines
Please help me with this and show the solution... Thanks!

so equation : (x-4)^2+(y-1)^2=2^2
expand it to get other forms .

Hi Lance,
Statement on line 2 beginning radius=2 is incomplete without additional info.Missing something like the equation of the tangent line?
